North Sonoma Mountain Regional Park and Open Space Preserve is the newest addition to Sonoma County's park system. The 820-acre park offers sweeping views of the county and beyond and includes a 4-mile Bay Area Ridge Trail connection to Jack London State Historic Park.

All trails are open to hikers, bikers and equestrians, though bikes on the Ridge Trail are limited to the first 2 miles. We suggest equestrians first visit without their horse trailers so they can acquaint themselves with the park entrance. The first 800 feet of the Ridge Trail are wheelchair accessible. The trail segment leads to a creekside picnic area in the redwoods. Dogs are not permitted on trails at this time.
